Analysis

Matthew Daniel Hwang is an examiner in Tech Center 2800 and Art Unit 2831. With 145 resolved cases, the examiner has a documented history of prosecution outcomes. The allowance rate is 84.1 percent, which serves as a benchmark for the probability of receiving a patent grant. Additionally, the median days to allowance is 1087, providing a clear expectation for the duration of the examination process.

The interview lift for this examiner is 7.2 percent. This figure indicates that applications with an interview see an increase in the allowance rate compared to the 84.1 percent baseline. Practitioners should factor this 7.2 percent lift into their strategy, especially when considering the 1087-day median pendency. In Art Unit 2831, the 145 resolved cases suggest that while the allowance rate is already 84.1 percent, direct communication can still provide a marginal benefit for applicants seeking to ensure a positive outcome.
